Factors driving adoption and constraining the non-adoption of biofortified orange fleshed sweet potatoes (OFSP) among farmers in Abia State, Nigeria
(2020-09-22)
This study sought to determine the factors that drive the adoption and constrain the non-adoption of Orange Fleshed Sweet Potato (OFSP) varieties among farmers in Abia State, Nigeria. Multistage sampling procedure was used in selecting sixty sweet potato farmers (thirty adopters and non-adopters each). Participatory tools such as structured interview schedule, key informant interviews and personal observation were employed for quantitative and qualitative data collection. The data were analysed using descriptive ...

Volatile Compounds effects in Industrial Food Recipes using Food Pairing Method
(2020-12)
The present study aims to investigate the flavour pairing-methodology for product development in an international acting company. Besides the sensory tests, analytical investigations and algorithmic works are part of the research.
In this study, original food ingredients (eighty-seven flavouring ingredients) which are mostly consumed in Turkey and some of them are currently used in a worldwide acting company (Headquarter in Germany with a branch in Turkey) were examined to postulate which ingredients should be brought ...

Effects of agroecological practices on soil organic carbon sequestration using synchronic and diachronic approaches in Madagascar
(2020-06-16)
Soil organic carbon (SOC) sequestration in agricultural systems is a key indicator of soil fertility improvement and climate change mitigation at the global scale. In Madagascar, the effect on SOC sequestration of converting from traditional practices to agroecological ones remains unclear. The objectives of this study were (i) to assess the impact of agroecological practices, such as agroforestry (AF), tree plantation (TP) and improved farming practices (IFPs), on SOC sequestration at the field level; and (ii) to ...

Morphology, biochemistry, and management of Russian olive (Elaeagnus angustifolia L.) accessions in Gilgit-Baltistan, northern Pakistan
(2020-07-30)
Russian olive (Elaeagnus angustifolia L., Elagnaceae) is a native multi-purpose medicinal shrub or tree of Asian regions and an integral component of high altitude terraced agroforestry systems of Gilgit-Baltistan, northern Pakistan. The strong increase in deforestation, urbanisation, and the loss of ethnically-based medication practices in local communities are gradually leading to depletion of its stands and knowledge of its use. In view of these circumstances, this study was undertaken to characterise Russian olive ...

Variation in baobab (Adansonia digitata L.) root tuber development and leaf number among different growth conditions for five provenances in Malawi
(2020-08-21)
The baobab tree is an underutilised indigenous fruit tree in sub-Saharan Africa which, at the same time is vulnerable to overexploitation in areas close to centres of demand, as currently baobab use is limited to wild, baobab trees. Baobab seedlings are known to form root tubers, but little is known about their growth characteristics and its yield potential. This study aims to investigate the root tuber and leaf development of baobab seedlings grown from seeds of five provenances, sown at three different planting ...

How do management practices and farm structure impact productive performances of dairy cattle in the province of Pichincha, Ecuador
(2020-11-11)
The combination of "ancestral knowledge" and modern agricultural techniques are increasingly used by Andes farmers, demonstrating its great importance as an ideal alternative to achieve international standards of productivity and sustainability. Pasture management has demonstrated its relevance in terms of milk volume and quality in farms located in the Ecuadorian highlands, showing a wide range of types of forage resource use, in its constant search for better animal yields from the occupancy rate. However, while ...

An approach to the use of technology in the cocoa-growing sector: a look from the producer
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-06)
A study was conducted to keep scientific record of the challenges and opportunities of the insertion of a mobile app for cocoa producers in the Colombia region as a prospective tool or strategy for technological transfer and appropriation into that sector. A survey with structured and semi-structured questions that pertained to cocoa producer men and women was conducted. The questions were related to the general conditions of their labour activities and were discriminant in the following categories: cocoa-grower ...

Are there gender differences in access to and demand for East Coast fever vaccine? Empirical evidence from rural smallholder dairy farmers in Kenya
(2020-11-03)
Women lag in the adoption of agricultural innovations compared to men, mainly due to gender inequalities in access to complementary inputs, capital, and knowledge/information. The Infection-and-Treatment-Method (ITM) is considered a safe and effective method of controlling East Coast fever. However, since its commercialisation in Kenya differences in demand for this vaccine among smallholder men and women dairy cattle keepers have not been assessed. Using a sample of 448 respondents, we used an Average-Treatment-Effect ...

Can calcium sprays alleviate jelly seed in mango fruits?
(2020-03-27)
Jelly seed is a major challenge in mango production leading to enormous losses in the value chain. This internal fruit disorder is characterised by disintegration of cells, consistency of jelly and broken cells. Calcium plays an important role in enhancing tissue stability and firmness thus reducing cell disintegration. A two-year field study was conducted in Embu County, Kenya using ‘Van Dyke’ cultivar trees of approximately 10 years old. The objective of the study was to investigate the effect of varied sources of ...

Characterisation of productivity and diseases affecting dairy goats in smallholder systems of Greater Thika Region, Kenya
(2020-11-18)
The current cross-sectional study aimed at characterising the productivity and diseases affecting dairy goats kept by smallholder farmers in three sub-counties in Thika Region, Kenya. Standard questionnaires were administered to 240 farmers through face-to-face interviews and the outputs were analysed using descriptive and inferential statistics. The farmers mainly kept crosses of Toggenburg (45.9 %), Kenyan Alpine (29.5 %) and Saanen (17.4 %) dairy goats. The average dairy goat flock size was 4.5 (range 1–23) and ...
